Font download crashes on Windows: unzip command not available

[blueberrycongee]

Problem

electron/main.ts lines 753 and 768 use the Unix unzip command to extract font files:

execSync(`unzip -l "${tmpZip}"`, { encoding: "utf-8" });  // line 753
execSync(`unzip -jo "${tmpZip}" "${innerPath}" -d "${fontsDir}"`, ...);  // line 768

Windows does not have unzip installed by default. execSync will throw an error, crashing the font download flow.

Suggested fix

Use a Node.js library (e.g. yauzl, adm-zip) or PowerShell's Expand-Archive on Windows.
